Yes, definitely semibreve-semibreve. An upstem to the left unambiguously denotes a c.o.p. ligature (cum opposite proprietate). This takes precedence over the other rules for parsing ligatures, including the one that says that "everything from the second note to the penultimate note is a breve unless otherwise notated".
